Solid-state quantum emitters with spin registers are promising platforms for quantum communiion, yet few emit in the narrow telecom band necessary for low-loss fiber networks. Here, we create and isolate near-surface single vanadium dopants in silicon carbide (SiC) with stable and narrow emission in the O band, with brightness allowing cavity-free detection in a wafer-scale material.

Silicon Carbide The utility of silicon oxide coatings is limited by its applicability for good barrier properties. There appears to be a fundamental limit to how effective SiO 2 thin films can be to water vapor transport9. Silicon carbide, in this case, has superior performance as a barrier to water vapor as compared to SiO 2. For example,
